What are the JavaScript version numbers and which version of ECMAScript do they match?

Question

I searched the JavaScript history and found out that the ECMAScript specification is based on it. Thus, JavaScript is older than ECMAScript, but seems to have subsequently become the embodiment of this specification.

So I have found out so far that:

• JavaScript 1.0 was the first version
• ECMAScript 3 implemented in JavaScript 1.5
• ECMAScript 4 has not been completed.
• ECMAScript 5 is implemented in JavaScript 1.8.5
• ECMAScript 6 was released in 2015 (which is why it is also called ECMAScript 2015).
• ECMAScript 7 was released 2016 (therefore it is also called ECMAScript 2016)

After version 1.8.5 of JavaScript, I cannot find higher version numbers. What versions of JavaScript implement ECMAScript 6 or 7?
